It's a "sad day in America" when people participating in a march to support police have to worry about being assaulted or called a racist, former Acting ICE Director Tom Homan said Saturday.

Homan, appearing on "Fox & Friends Weekend," said that's part of why he strongly supports Saturday's We Back Blue March in Washington, D.C.

HUNDREDS MOURN DAVID DORN, RETIRED ST. LOUIS POLICE CAPTAIN KILLED IN LOOTING

A video promoting the march notes there are "900,000 officers in the USA to protect 325 million people," and also pays tribute to retired St. Louis police Capt. David Dorn, who was shot and killed by a looter during protests against police brutality.

"I'm going to go up there, and I’m going to march with this group. I'm also going to speak. I was asked to do that, and I'm going to do it because I want to speak for the men and women of this nation that support police but are afraid to say so," Homan said.

The former police officer said he believes the nationwide unrest and continuing Black Lives Matter demonstrations sparked by the death of George Floyd in Minneapolis may scare off some people who would like to show their support for police.

"They are afraid of what they have seen the last two weeks in Washington, D.C. They are afraid that some violence may occur," Homan said.

"It's a sad day in America, when an American taxpayer cannot support our men and women in law enforcement without fear of violence. ... And it's a sad day when people that want to go show their support for law enforcement are afraid to do so out of fear they may be attacked and may be called racist."

"There is no reason we can't denounce racism – it’s a terrible thing. Denounce racism, but at the same time defend the men and women who defend this nation and our communities, and protect us every single day across this country," Homan said.
